I have an old Intel D845PEBT2 motherboard and a northwood P4 3.06 GHz 533mHz FSB processor. I was thinking of upgrading to get games like Half Life 2 to run better, but I'm sort of walled in. I have a GeForce 4 ti4200, but the board is AGP 4X, so I thought about swapping motherboards to get an AGP 8X slot and faster memory... But would it be worth it? Will the processor just run pc3200 ram at pc2700?
